GridView, DataTable, and List sorting, SQL paging supports CheckBox Selection

A new gridview is encapsulated, and the following functions are supported: 1. Select a record in the checkbox and specify the position of the checkbox.
2. list, dataset, and able sorting are supported.
3. the header icon appears during sorting.
4. It encapsulates pageindexchanged and databind, and does not need to be written on every page.
5. Supports paging controls such as SQL paging and aps tutorial netpager. Note: many functions are not added, because a lightweight gridview is required to generate near-Possible code. In addition, the highlighted feature is implemented by jquery. Therefore, the jquery Runtime Library is required for use. Code 1: Secondary object to implement sort sorting. (In fact, this part of the function can be implemented using linq, which is much simpler. When this class has been used for a long time, I am too lazy to change it)
